Ducks swim past dead fish floating on a lake in the 3 de Febrero Park in Buenos Aires, Argentina, Wednesday, Jan. 8, 2014. According to the park's Director, Alejandro Perez, the lake's large fish are affected by the current heat wave, as the rising temperature is lowering the oxygen level in the water. He added that no ducks, geese or small fish have died, and that a pollution hypothesis was discarded following tests in December. The park, also known as Bosques de Palermo, is one of the city's largest parks, known for its lakes and rose gardens and is popular with tourists.
